Peter Maydell bde8adb808 target/i386: Remove dead assignment to ss in do_interrupt64() 
Coverity points out that in do_interrupt64() in the "to inner
privilege" codepath we set "ss = 0", but because we also set
"new_stack = 1" there, later in the function we will always override
that value of ss with "ss = 0 | dpl".

Remove the unnecessary initialization of ss, which allows us to
reduce the scope of the variable to only where it is used.  Borrow a
comment from helper_lcall_protected() that explains what "0 | dpl"
means here.
